The brand name is Froggybank. It is NOT a bank, but a money saving site. Froggybank is a bit like PiggyBank, but with a frog instead of a pig. Do something simple, not too much like a cartoon.

Logo will consist of a frog image and the text "froggybank"

So, we need the frog image, which is the crucial bit. This frog needs to be professional, neat, green, preferably have a piggybank like look or concept. The frog also needs to be a happy and likeable one. This frog should look good on T-Shirts, mugs etc. This froggy will also be used across various sections of the website.
